Graywater drain valve sticking
I tried a search but didn't find this topic. The slider or gate valve for our graywater tank drain is getting hard to pull our or push in. Any suggestions as to an appropriate lube. Thanks in adv...

I put a grease fitting on mine, and pump a few ozs of grease in every other year, when it gets hard to move. It is usually my black dump valve that sticks first.
